3.3 Wiring Precautions
This section describes the procedures and precautions for wiring power cords.
3.3.1 Connecting the Power Cord
PS-3710A/PS-3711A Series AC Power Supply Type Connections
To avoid an electric shock, prior to connecting the PS-A unit’s power cord terminals to the
power terminal block, confirm that the PS-A unit’s power supply is completely turned OFF,
via a breaker, or similar unit.
Supplying a power voltage other than that specified will damage the power source and the
PS-A unit.
Since there is no power switch on the DC type unit, be sure to attach a breaker-type switch
to its power cord.
When the FG terminal is connected, be sure the wire is grounded.
• When the FG terminal is connected, be sure the wire is grounded. Not grounding
the PS-A unit will result in excess noise and vibration.
• The SG and FG terminals are connected internally in the PS-A unit.
When connecting the SG wire to another device, be sure that the design of the
system/connection does not produce a shorting loop.
The PS-A units is designed to use AC100 to 240V input. Supplying a power voltage other
than that specified will damage the power source and the PS-A unit.
